In general, embodiments of the invention relate to establishing trust between nodes based on node information maintained by a social manager. A node may require another node to perform a service. A node may obtain node information associated with multiple nodes that include the capability to perform the service. The node may identify the most trustworthy node to perform the service based on node ratings, node endorsements, and node review information generated by other nodes that have previously obtained services from the multiple nodes that include the capability to perform the service. The node may identify the node of the multiple nodes associated with the highest node rating, the most node endorsements, and the node review information that indicates the most successfully performed services. As a result the node may use the node information automatically generated by other nodes to identify the most trustworthy node to perform the service. Therefore, the efficiency of determining the trustworthiness of other nodes and reliability of selecting the most trustworthy nodes in a system may be improved.

The updated node information may be sent to the social manager via other and/or additional methods without departing from the invention.

The method may end following step 330.

To further clarify embodiments of the invention, non-limiting examples are provided in FIGS. 4A-4B. FIGS. 4A-4B show diagrams of operations performed by an example system over time in accordance with one or more embodiments of the invention. FIGS. 4A-4B may show a system similar to that illustrated in FIG. 1A. Actions performed by components of the system are illustrated by numbered, circular boxes interconnected with arrowed lines. For the sake of brevity, only a limited number of components illustrated in FIG. 1A are illustrated in FIGS. 4A-4B.

Example

Turning to FIG. 4A, consider a scenario in which a node included in a system registers with a social manager. The system includes a social manager (410) and three nodes, node A (400A), node B (400B), and node C (400B). The social manager (410) includes a social manager controller (412) and persistent storage (414). The persistent storage includes a node information repository (416). Node A (400A) and Node B (400B) have registered with the social manager (410), and therefore, at the point in time at the start of the example, the node information repository (416) includes node A information (420A) and node B information (420B).

At step 1, node C (400C) sends a message to the social manager controller (412). The message includes a request to register with the social manager (410). In response to obtaining the registration request, the social manager controller, at step 2, sends a message to node C (400C). The message includes a request for node information associated with node C (400C). In response to the message, at step 3, node C (400C) generates and sends node C information (420C) associated with node C (400C) to the social manager controller (412). The node C information (420C) includes a node identifier associated with node C (400C), node configuration information associated with node C (400C), and node capability information associated with node C (400C).

After obtaining node C information (420C) from node C (400C), at step 4, the social manager controller (412) updates the node information repository (416) so that the node information repository includes node C information (420C). At step 5, the social manager controller (412) sends registration confirmation to node C (400C). As a result, node C (400C) is able to use the social manager (410) to identify other nodes (e.g., 400B, 400A) to perform services based on nodes' associated trustworthiness indicated by the node information (e.g., 420A, 420B) included in the node information repository (416).

Turning to FIG. 4B, consider a scenario in which a node performs a service using another node in the system. The system includes a social manager (410) and three nodes, node A (400A), node B (400B), and node C (400B). The social manager (410) includes a social manager controller (412) and persistent storage (414). The persistent storage includes a node information repository (416). Node A (400A), node B (400B), and node C (400C) have registered with the social manager (410), and therefore, at the point in time at the start of the example, the node information repository (416) includes node A information (420A), node B information (420B), and node C information (420C).

At step 1, node A (400A) sends a message to the social manager controller (412) which includes a request to obtain the location of a nearest gas station. Node A (400A) does not include the capability to perform that service. Therefore, the message sent in step 1 includes a request to obtain node information associated with a node that includes the capability of identifying the location of the nearest gas station and provide the location to node A (400A). In response to obtaining the message, at step 2, the social manager controller (412) identifies that node B information (420B) and node C information (420C) include node capability information that indicate that node B (400B) and node C (400C) both include the functionality to provide the location of the nearest gas station to node A (400A). At step 3, the social manager controller (412) sends node B information (420B) and node C information (420C) to node A (400A). After obtaining node B information (420B) and node C information (420C), at step 4, node A (400A) compares node B information (420B) and node C information (420C) and identifies that node B information (420B) is associated with a higher node rating and more node endorsements than node C information (420C). Therefore, node A (400A) identifies node B (400B) to perform the service. At step 5, node A sends a request to obtain the nearest gas station to node A (400A) and provides the location of node A (400A). At step 6, node B (400B) identifies the nearest gas station to node A (400A), and, at step 7, provides the location of the nearest gas station to node A (400A). Node A (400A) goes to the location provided by node B (400B) and, at step 8, determines that the location is in fact a gas station and was within an appropriate distance from node A (400A). Based on the determination, at step 9, node A (400A) generates updated node information associated with node B (400B) that includes a high node rating, an endorsement, and a node review information that includes a description of the service performed by node B (400B). At step 10, node A (400A) sends the updated node information to the social manger controller (412). After obtaining the updated node information, the social manager controller (412), at step 11, updates node B information (420B) to include the updated node information generated by node A (400A).
